Chapter 134: AMOLED screen
After Shen Danqing's family played for a few days, they had to return to Huizhou, because Shen Danqing was going to work, and he couldn't never go to work.
After returning to the company, Shen Danqing instructed Dingtian Law Firm to sign a formal employment contract with Li Zhengyu. In fact, this contract is of little use to Changsheng Investment Group, but it has a great protective effect on employees. Changsheng Investment Group is a lifelong system, as long as the employee is not too much at fault, it will generally only be demoted, and the employee will not be easily dismissed.
Shen Danqing is different from ordinary people in two ways. First, he is a reborn, so his vision is a little higher than others.
Second, he is already the richest individual in China, so his pursuit of money is relatively weak. For him, earning 100 million is just an increase in numbers, anyway, he can't spend all his money in his life. On the contrary, he has always had a pathological pursuit of creating 10 million affluent middle-class employees. That's why there is a provision for tenured employees.
After the company signed a formal employment contract with Li Zhengyu, Shen Danqing instructed Dingtian Law Firm to send someone back to Hong Kong with Li Zhengyu to establish Julong Culture and Entertainment Communication Co., Ltd. It's still a little early to set up this company, and Shen Danqing didn't care too much about it, so he put this matter aside and didn't care about it, and dealt with the documents left over in the past few days wholeheartedly.
"Good! very good!" Shen Danqing applauded loudly with a RoM memory chip in his hand.
The Institute of Electronics has researched two chips, although they are both simple chips, but they are commonly used chips by Changsheng Investment Group, and now they can produce them themselves, so they don't need to spend money on imports. Saving money is one aspect, and the most important significance is that it indicates that Changsheng Investment Group has the ability to design and produce various types of chips.
The first chip is a power management chip. The power management chip is just a general term, in fact, due to the different use environments, the technical difficulty level of the circuit in it is also very different. For example, the technical difficulty level of the power management chip used in mobile phones and the power management chip used in ordinary small household appliances is N times worse.
The power management chip of small household appliances only cares when the power is turned on and off and how long it lasts, and it is only responsible for one or several simple functional circuits, and the function is very simple. The power management chip of the mobile phone is not only responsible for turning on and off the power on N times more functional circuits, but also has an additional task to save energy and power. With just such a task, its technical difficulty level is multiplied, and only some large companies can design and manufacture it.
The power management chip designed by the Institute of Electronics is the simplest functional chip. It can be used in small household appliances, which is still very practical for Changsheng Investment Group.
The second chip is the RoM memory chip, also known as the read-only memory chip. This kind of chip is used by the manufacturer to burn the pre-designed program or instruction into the production line with special tools. Once entered, it cannot be changed, and is generally used to save the more important system programs and i0 function Bois programs. It can also be used as a simple program memory that does not need to be changed, such as the memory of the storage control program in the small household appliances of Changsheng Investment Group is the RoM memory used. Because he does not have a programmable control unit that is open to the user, the user can only use the pre-defined function keys. Therefore, it is also ideal for using this type of memory.
With these two chips, coupled with the existing 16-bit general-purpose processing chip of Changsheng Investment Group, the circuit motherboard used in the small household appliances of Changsheng Investment Group has achieved all self-production. This is only the first step, and more and more functional circuit motherboards will be able to achieve full self-production in the future.
"Director Hong, what chips are you going to design next?" There are already three chips, and Shen Danqing is a little bit hopeful. So he immediately asked them what their next steps were.
"Boss, it's still a memory chip. There are many types of memory chips, and they are also the most used functional chips in electronic circuits. In terms of large types, it can be divided into read-only memory chips, random memory chips and FLAsH flash memory chips. Under these large types of chips, they are divided into various types of chips according to different functions and manufacturers. If we had to design each type, it would take many years to do it. Hong Tao complained to him indirectly. Seriously, the task of the Electronics Research Institute is really very heavy, and the most important thing is that they lack personnel.
At present, there are only more than 200 people in electronic research, including miscellaneous work, and only 125 real electronic engineers, including Hong Tao himself. Just such a few people, they are not only responsible for chip design, but also responsible for the circuit board design of other companies in the company. The task is very heavy, and in short, there is a lot to do. Over time, employee aversion to work will continue to accumulate, resulting in extreme productivity failures. How to solve this problem? For Hong Tao, this is a difficult proposition.
The electronics students of Huachuang Vocational and Technical College are still in a state of studying and interning with electronic engineers, not only can not help, but also share a lot of their energy and time. However, in order to have more people to share their work in the future, they have to endure.
"Well, you have a lot of problems. So be it, you can't just give without a reward. Director Hong, every time you successfully design a chip, you can charge an appropriate intellectual property fee and share it in the cost of each chip. How much exactly? It needs to be discussed at a conference. Because the cost of these chips needs to be paid by other companies, I also want to listen to their opinions. But there will definitely be, and you can fight for the amount of money at the meeting, I'm just setting the rules. A rule that takes care of you. Director Hong, are you satisfied?" Shen Danqing thought of this method in order to improve their enthusiasm in order to improve their enthusiasm. One of the responsibilities of being a boss is to continuously improve the motivation of employees.
"Satisfied, very satisfied! Thank you, boss! If I tell them the good news, they will be very grateful to the boss." I believe that their enthusiasm for work will also increase a lot. Hong Tao thanked again and again, and bowed with a big bow to show his deep gratitude.
Shen Danqing saw Director Hong making such a big salute, and hurriedly shook his hand to stop it, and said in his mouth: "Thank me for what to do, this is what I should do, a qualified boss is to always think about employees." In this way, employees will work better for their bosses. ”
"In short, it's the boss's benevolence. On behalf of all of you, I thank you. Hong Tao still insisted on thanking. Shen Danqing had no choice but to let him.
"There is one thing that is not self-produced for small household appliances, and that is the LCD screen. I've long been unaccustomed to that kind of rustic TN LCD screen, but at that time we still needed to import, and we couldn't produce it ourselves, so we had to endure it. Now that we have the conditions to produce it ourselves, we will replace it immediately and use a higher level of technology. Speaking of small household appliances, Shen Danqing mentioned another thing.
"Boss, this doesn't seem to be our task!" Hong Tao cautiously reminded the boss.
"Alas, yes, it's not your job. However, the drive circuit and screen control circuit also need to be designed by you. This time, I plan to use AMOLED liquid crystal technology, and use a completely different technology from other countries. Shen Danqing had already entered deep thinking, completely ignoring whether Hong Tao could understand or not.
"Boss, what is AM0LED!" Hong Tao heard a new term from the boss again, and couldn't help but ask curiously.
"AMOLED is the abbreviation of English, and the Chinese meaning is to directly drive a single prime point display technology. Don't you notice the word LED? LEDs are light-emitting diodes, and each light-emitting diode is a pixel. Each light-emitting diode is controlled by a control circuit to emit various colors of light, so as to achieve the purpose of displaying images and text. As long as this diode is so small that it is not visible to the naked eye, it is able to display very clear and detailed text and images. As long as the LEDs are small enough, the clarity is even greater than the same words and images we see with the naked eye.
You have seen the glass curtain wall display screen of our headquarters building, that one square glass is a pixel, and the AM0LED technology we want to study is the same as the glass curtain wall display technology of the headquarters building. Shen Danqing crackled like a teacher who was lecturing.
"Boss, when you say this, it seems that there is nothing to do with LCD? The glass curtain wall of our headquarters building does not have LCD technology. Hong Tao listened carefully to the boss and found that AMOLED didn't seem to need liquid crystal technology, so he said to Shen Danqing.
No, it's still different, the light-emitting diode of the AMOLED screen is made by photolithography, so it can't emit any color of light,...... I'm so confused by your question, I don't know how to answer that question. After all, Shen Danqing has no goods in his stomach, and he can't speak as he speaks.
"Boss, listening to your explanation, I know how to display color technology. Hong Tao is an electronics engineer, and designing various functional circuits is his specialty, so he got inspiration from Shen Danqing's explanation.
"Oh, tell me how to display color technology. Shen Danqing was interested in Hong Tao's words.
"Boss, it's very simple, a single light-emitting diode can't emit any color of light, but it's easy to emit a monochromatic light. If we integrate three light-emitting transistors, one that emits red, one green, and one blue, into one pixel to form three primary colors, can't we emit light of any color?" Hong Tao said his thoughts.
"That's it, don't you need any filters and LCD screens?" Shen Danqing asked Hong Tao puzzled.
"No, these three light-emitting transistors are so small that we can't see them with the naked eye, so we can't see the mixed colors with our eyes, not the light emitted by a single transistor. Hong Tao explained why. In fact, this is the shortcoming of our eyes, which is easy to be confused. Scientists have taken advantage of this shortcoming and invented many useful things.
